<h2 id="installation">Installation</h2>
<p>You can download the latest version of Chart.js from the <a href="https://github.com/chartjs/Chart.js/releases/latest" target="_blank">GitHub releases</a> or use a <a href="https://cdnjs.com/libraries/Chart.js" target="_blank">Chart.js CDN</a>. Detailed installation instructions can be found on the <a href="getting-started/installation.html">installation</a> page.</p>
<h2 id="creating-a-chart">Creating a Chart</h2>
<p>It&apos;s easy to get started with Chart.js. All that&apos;s required is the script included in your page along with a single <code>&lt;canvas&gt;</code> node to render the chart.</p>
<p>In this example, we create a bar chart for a single dataset and render that in our page. You can see all the ways to use Chart.js in the <a href="getting-started/usage.html">usage documentation</a></p>
